In case you want to use the current in-development version of lxml,
you can get it from the github repository at
https://github.com/lxml/lxml . Note that this requires Cython to
build the sources, see the build instructions on the project home
page. To the same end, running easy_install lxml==dev will
install lxml from
https://github.com/lxml/lxml/tarball/master#egg=lxml-dev if you have
an appropriate version of Cython installed.
